Type B Isospan

Izospan Type B is a two-layer vapor barrier material used as a protective layer against vapor and moisture in internal building structures. The product is designed to protect thermal insulation layers in roofs, walls, ceilings, intermediate floors, and floor structures from water vapor coming from the indoor space. Izospan B helps reduce the risk of condensation inside the insulation layer, maintain thermal insulation performance, and extend the service life of building structures. The material has one smooth side and one textured side; this structure helps retain condensation droplets and allows them to gradually evaporate later. Izospan B is a practical and reliable solution for residential buildings, attics, frame structures, internal walls, ceiling systems, and insulated floors. Lightweight, flexible, and easy to install, this product provides long-term vapor protection for construction and renovation works.
